/**
 *  A Timestamp represents a point in time independent of any time zone or local
 *  calendar, encoded as a count of seconds and fractions of seconds at
 *  nanosecond resolution. The count is relative to an epoch at UTC midnight on
 *  January 1, 1970, in the proleptic Gregorian calendar which extends the
 *  Gregorian calendar backwards to year one.
 *
 *  All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
 *  second table is needed for interpretation, using a [24-hour linear
 *  smear](https://developers.google.com/time/smear).
 *
 *  The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
 *  restricting to that range, we ensure that we can convert to and from [RFC
 *  3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
 *
 *  # Examples
 *
 *  Example 1: Compute Timestamp from POSIX `time()`.
 *
 *      Timestamp timestamp;
 *      timestamp.set_seconds(time(NULL));
 *      timestamp.set_nanos(0);
 *
 *  Example 2: Compute Timestamp from POSIX `gettimeofday()`.
 *
 *      struct timeval tv;
 *      gettimeofday(&tv, NULL);
 *
 *      Timestamp timestamp;
 *      timestamp.set_seconds(tv.tv_sec);
 *      timestamp.set_nanos(tv.tv_usec * 1000);
 *
 *  Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
 *
 *      FILETIME ft;
 *      GetSystemTimeAsFileTime(&ft);
 *      UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
 *
 *      // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
 *      // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
 *      Timestamp timestamp;
 *      timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
 *      timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
 *
 *  Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
 *
 *      long millis = System.currentTimeMillis();
 *
 *      Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
 *          .setNanos((int) ((millis % 1000) * 1000000)).build();
 *
 *
 *  Example 5: Compute Timestamp from current time in Python.
 *
 *      timestamp = Timestamp()
 *      timestamp.GetCurrentTime()
 *
 *  # JSON Mapping
 *
 *  In JSON format, the Timestamp type is encoded as a string in the
 *  [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
 *  format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
 *  where {year} is always expressed using four digits while {month}, {day},
 *  {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
 *  seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
 *  are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
 *  is required. A proto3 JSON serializer should always use UTC (as indicated by
 *  "Z") when printing the Timestamp type and a proto3 JSON parser should be
 *  able to accept both UTC and other timezones (as indicated by an offset).
 *
 *  For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
 *  01:30 UTC on January 15, 2017.
 *
 *  In JavaScript, one can convert a Date object to this format using the
 *  standard
 *  [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
 *  method. In Python, a standard `datetime.datetime` object can be converted
 *  to this format using
 *  [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
 *  the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
 *  the Joda Time's [`ISODateTimeFormat.dateTime()`](
 *  http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
 *  ) to obtain a formatter capable of generating timestamps in this format.
